I keep a battery tender on all my cars. I disconnected the tender and closed the trunk. Got inside and it wouldnt start. I tried to open the trunk and llock the doors with the phob, but it wouldnt work. I assumed it was the phob and got the other phob, but same result. I used the trunk button on the dash and that did not work either. I assume it is something with the battery? but I can't get the trunk open. Is there another way to open the trunk with no power other than pulling the back seat? Has any one else had this problem?
